Katz spoke before a U.S. Senate appropriations subcommittee looking at the current capabilities - and future cybersecurity funding needs - of several government agencies, including the Department of Homeland Security.

Katz's testimony focused on cybersecurity workforce development.

"Developing an adequately prepared cybersecurity workforce is a daunting challenge - put simply, demand is far outstripping supply," said Katz in the second half of the hearing, which partially focused on academia and the private sector and their roles in working together to grow the cybersecurity field.

The hearing also featured testimony from top cybersecurity officials from the U.S. Citizenship and Immigration Services, U.S. Customs and Border Protection, and the Secret Service on what their agencies are up to and what their budget needs are. Part of their testimony focused on the importance of training college students to someday work in cybersecurity.

"[The University of Maryland is] doing great work in preparing the cyberworkforce," said U.S. Sen. Chris Coons, who represents Delaware and is a member of the subcommittee, of the university’s cybersecurity programs.
